Look up "blue ocean event". The BOE could lead to the loss of the jet stream in 10-20 years. After that, God only knows what is going to happen. The really big problem is that we won't know where the rain will fall, and so we won't know where to plant, and so we could have global famine. If you think covid was bad, you ain't seen nuthin'. And even that will not necessarily lead directly to the collapse of civilization, but I'm not optimistic about the ability of our political leaders to handle the situation gracefully and without starting WW3.
